transmitter away from the rear
bumper detection area or turn the
liftgate mode to OFF when
cleaning or working near the rear
bumper to avoid accidental
opening.
. Do not sweep your foot side
to side.
. Do not keep your foot under the
bumper; the liftgate will not
activate.
. Do not touch the liftgate until it
has stopped moving.

Power Assist Steps
{Warning
To avoid personal injury or
property damage, before entering
or exiting the vehicle, be sure the
power assist step is fully
extended. Do not step on the
power assist step while it is
moving. Never place hands or
other body parts between the
extended power assist step and
the vehicle.
If equipped, the power assist steps
will deploy when the door is opened
and automatically retract
three seconds after the door is closed. The power assist steps will
retract immediately if the vehicle
starts moving.
Disable the power assist steps
before jacking or placing any object
under the vehicle. Too much ice
buildup may prevent deployment of
the power assist steps. Check the
step position before exiting the
vehicle. If this happens, disable the
power assist steps, clear the ice,
then enable the assist steps and
confirm normal function prior to use.
Keep hands, children, pets, objects,
and clothing clear of the power
assist steps when in motion. The
steps will reverse direction if they
encounter an obstruction when
opening or closing. Remove the
obstruction, then open and close the
door on the same side to complete
the motion of the assist steps. If the
obstruction is not cleared, the assist
steps remain extended while driving.

{Warning
A seat belt that is improperly
routed, not properly attached,
or twisted will not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. After raising the
rear seatback, always check to be
sure that the seat belts are
properly routed and attached, and
are not twisted.
3. Reconnect the center seat belt mini-latch to the mini-buckle.
Do not let it twist.

Seat Belts
This section describes how to use
seat belts properly, and some things
not to do.
{Warning
Do not let anyone ride where a
seat belt cannot be worn properly.
In a crash, if you or your
passenger(s) are not wearing
seat belts, injuries can be much
worse than if you are wearing
seat belts. You can be seriously
injured or killed by hitting things
inside the vehicle harder or by
being ejected from the vehicle. In
addition, anyone who is not
buckled up can strike other
passengers in the vehicle.
It is extremely dangerous to ride
in a cargo area, inside or outside
of a vehicle. In a collision,
passengers riding in these areas
are more likely to be seriously
injured or killed. Do not allow
(Continued)
Warning (Continued)
passengers to ride in any area of
the vehicle that is not equipped
with seats and seat belts.
Always wear a seat belt, and
check that all passenger(s) are
restrained properly too.
This vehicle has indicators as a
reminder to buckle the seat belts.
See Seat Belt Reminders 0150.

Also make sure the child
restraint is not trapped under
the vehicle head restraint.
If this happens, adjust the head
restraint. SeeHead Restraints
0 66.
6. Restart the vehicle.
The passenger sensing system may
or may not turn off the airbag for a
child in a child restraint depending
upon the child’s size. It is better to
secure the child restraint in a rear
seat. Never put a rear-facing child
restraint in the front seat, even if the
ON indicator is not lit.If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting in
the front outboard passenger seat,
but the OFF indicator is lit, it could
be because that person is not sitting
properly in the seat or that the child
restraint locking feature is engaged.
Use the following steps to allow the
system to detect that person and
enable the front outboard passenger
frontal airbag: 1. Turn the vehicle off. 2. Remove any additional material
from the seat, such as
blankets, cushions, seat
covers, seat heaters, or seat
massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on the seat
cushion, with legs comfortably
extended.
5. If the shoulder portion of the belt is pulled out all the way,
the child restraint locking
feature will be engaged. This
may unintentionally cause the
passenger sensing system to
turn the airbag off for some
adult-sized occupants. If this
happens, unbuckle the belt, let
the belt go back all the way,
and then buckle the belt again
without pulling the belt out all
the way.
6. Restart the vehicle and have the person remain in this
position for two to three minutes
after the ON indicator is lit.

Caution (Continued)
Do not fold the rear seatback
when the seat is occupied. Do not
fold the empty rear seat with a
seat belt buckled. This could
damage the seat belt or the seat.
Unbuckle and return the seat belt
to its stowed position, before
folding the seat.
The vehicle is equipped with a front
center airbag in the inboard side of
the driver seat. Even with a front
center airbag, a child restraint can
be installed in any second row
seating position.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint 0110.
1. Attach and tighten the lower attachments to the lower
anchors. If the child restraint
does not have lower
attachments or the desired
seating position does not have
lower anchors, secure the child
restraint with the seat belts and top tether when recommended
by the child restraint
manufacturer. Refer to your
child restraint manufacturer
instructions and the
instructions in this manual. For
the third row outboard seating
positions, if the head restraint
interferes with the proper
installation of the child
restraint, then the head
restraint may be removed. See
“Head Restraint Removal and
Reinstallation under
Lower
Anchors and Tethers for
Children (LATCH System)
0 111.
1.1. Find the lower anchors for the desired seating
position.
1.2. Put the child restraint on the seat.
1.3. Attach and tighten the lower attachments on the
child restraint to the lower

tether to the top tether anchor.
Refer to the child restraint
instructions and the following
steps:
2.1. Find the top tether
anchor.
For the third row seat,
